A curvature adjustment method is applied to an arc-shaped stator vane segment having a plurality of stator blades disposed side by side on the outer peripheral side of an arc-shaped inner coupling member. In the curvature adjustment method, a jig preparation step, a jig mounting step, and a curvature adjustment step are executed. In the jig preparation step, a curvature adjustment jig and a distance adjustment mechanism are prepared. In the jig mounting step, with the distance adjustment mechanism placed on the inner peripheral side of the inner coupling member, a first end is fixed at a first position of the inner coupling member, and a second end is fixed at a second position of the inner coupling member. In the curvature adjustment step, the distance adjustment mechanism is operated after the jig mounting step to change the distance between the first and second ends of the curvature adjustment jig.

A combustor is provided with a combustion liner () in which a combustion gas flows through the inner peripheral side and a plurality of through-holes () are formed, and a sound attenuator () having a space-forming member () configured to form a space (S) connected to the plurality of through-holes () at the outer peripheral side of the combustion liner (). The space-forming member has a main body having an opening configured to bring an outside and the space in communication with each other, and a lid joined to an outer surface of the main body via a welded portion and configured to protrude outward and close the opening.

A combustor pipe is linked to a vane shroud in which a vane is provided, and includes an inlet, an outlet, an inner pipe of which an inner space is a flow path for passing a combustion gas, a first cooling flow path through which a cooling medium passes being formed inside a wall that forms the flow path; and an outer pipe on an outer circumference of the inner pipe and secured to the inner pipe. A second cooling flow path through which a cooling medium passes and which is connected to the first cooling flow path near the outlet of the combustor pipe is formed between an outer circumferential surface of the inner pipe and an inner circumferential surface of the outer pipe, and a cooling promoting structure is formed on the outer pipe, inside the second cooling flow path near the first cooling flow path.

A combustor is provided with a combustion liner () in which a combustion gas flows through the inner peripheral side and a plurality of through-holes () are formed, and a sound attenuator () having a space-forming member () configured to form a space (S) connected to the plurality of through-holes () at the outer peripheral side of the combustion liner (). A method of repairing a combustor involves executing: an opening step of opening a portion of the space-forming member () in contact with the outside and bringing the outside and the space (S) in communication with each other; a cylinder repair step of repairing the combustion liner (); a foreign substance removal step of removing foreign substances in the space (S) from the opening () opened in the opening step to the outside, after the cylinder repair step; and a closing step of closing the opening () using a lid (), after the foreign substance removal step.

An evaluation information collecting system includes a storing device storing evaluation information evaluating a certain point, a presentation device for presenting the evaluation information, and an evaluation information collector for acquiring evaluation information associated with a point through which a moving body passes and causing the presentation device to present the evaluation information, and the evaluation information collector includes an evaluation information acquirer for acquiring the evaluation information associated with the point through which the moving body passes from the storing device, a validity determiner for determining validity of the evaluation information based on status information representing a status of the moving body or a user passing through the point associated with the evaluation information, and a change content generator for changing content of the evaluation information in the storing device such that the evaluation information determined to be invalid is not easily presented.
